2,4-Dihydroxybenzophenone Chemical Properties,Usage,Production

Chemical Properties

yellow crystalline powder

Uses

Novel mordent and disperse azo dyes were prepared by the coupling of various diazo solutions of aromatic amines with 2, 4-dihydroxybenzophenone. The ultraviolet absorbing monomers were synthesized by reaction of 2, 4-dihydroxybenzophenone with glycidyl acrylate and glycidyl methacrylate. Two new polymerizable stabilizers, 4-benzoyl-2-(α-piperidino-2-chlorobenzyl)-3-hydroxyphenyl acrylate (BPBHA) and corresponding methacrylate (BPBHMA), were synthesized and characterized from 2,4-Dihydroxybenzophenone. a polymerizable UV-stabilizer, 2-hydroxy-4-(3-methacryloxy-2-hydroxylpropoxy) benzophenone (BPMA), was synthesized using 2, 4-dihydroxybenzophenone (UV-0) and glycidyl methacrylate (GMA).

Uses

2,4-Dihydroxybenzophenone is an metabolite of Benzophenone (B204980), an compound used in the manufacturing of antihistamines, hypnotics and insecticides.

Uses

Ultraviolet light absorber, especially in paints and plastics.

Definition

ChEBI: 2,4-Dihydroxybenzophenone is a member of benzophenones.

Preparation

Obtained by condensation of benzanilide with resorcinol in the presence of zinc chloride and phosphorous oxychloride at 130–140° for 1 h (25%).

Contact allergens

BZP-1 is used, for example, in paints, plastics, and nail varnishes.

Safety Profile

Poison by intravenous and intraperitoneal routes. Mildly toxic by ingestion. An eye irritant. When heated to decomposition it emits acrid smoke and irritating fumes.

Purification Methods

Recrystallise it from MeOH. [Beilstein 8 IV 2442.]
